How to Disable BIOS Memory for Windows

by TS Jordan ; Updated February 10, 2017

Basic input output system is a low-level operating system that controls certain facets of your computer's hardware, such as the processor speed and memory timings. Disabling the BIOS memory settings such as the shadowing and cacheable settings will help to improve performance on some older operating systems. These BIOS memory settings are throwbacks from earlier systems, which are no longer necessary under Windows.

Restart your computer.

Press the key indicated during the start-up messages to enter BIOS. This key is typically either Esc or one of the F function keys.

Navigate to the Advanced settings menu by pressing the left and right arrow keys.

Use the up and down arrow keys to highlight the settings for Shadowing and RAM Cacheable. Press Enter after highlighting both entries and select the Disabled option.

Press Esc then press Y to exit and save changes.
